Plutarch is a typed eDSL in Haskell for writing efficient Plutus Core validators.

Plutarch written validators are often significantly more efficient than Plutus Tx written validators. With Plutarch, you have much more fine gained control of the Plutus Core you generate, without giving up any type information.

To put things into perspective, one validator script from a large production contract was rewritten in Plutarch, changed from Plutus Tx. Here's the comparison between the Plutarch script's execution cost compared to the Plutus Tx script's execution cost. These numbers were gathered by simulating the whole contract flow on a testnet:

More benchmarks, with reproducible code, soon to follow.

• Add this repo as a source repository package to your cabal.project.
• Add the plutarch package as a dependency to your cabal file.

This package takes in a flag, development, that defaults to false. It's used to turn on "development mode". Following is a list of effects and their variations based on whether or not development mode is on.

You can turn on development mode by passing in the development flag in your cabal.project file:

package plutarch
  flags: +development

See the plutarch-benchmark library for how to benchmark plutarch, and benchmarking your own scripts.

Contributions are more than welcome! Alongside the User guide above, you may also find the Developers' guide useful for understanding the codebase.
